are in contact therewith The pillow can be moved back and forth so thatthe entire surface encounters the rapidly revolving brushes. The brushesremove the particles of dust and the like from the surface of thepillows which particles are taken up by the current of air flowing frgmbranches 9 and 10 and are delivered in the direction of the arrows andare carried through the opening 4 into the hood 18'and conduit 17 by theair flowing to the'suction side of the blower 16.

V 15 and thence to the dust bag in the dust house. The dust bag acts asascreen or filter removing the particles of dust from the air as it flowsthrough the dust bag. 7 The cleaned air then delivers from the dust'house through the conduits 12 and 11 and then is delivered through thebranches '9 and 10 tothebrushes as before. p

The air continuously circulating as described takes up the particlesremoved from the pillows by the 'brushesand carries them to the dust bagwhere the air is purged. The rapidly moving air also tends to removesome of the particles'from the pillows in conjunction with the beatingand-scouring action of the brushes. One of the important features ofthis form of. the construction is the fact that the air is guided aroundthe revolving brushes and travels in the same direction as the peripheryof the revolving Asa result of this arrangement the dus't is rapidlyand. efiiciently removed from the pillows and taken'to the dust housewithout permitting any of it to escape into the surrounding atmosphere.

' r-In the form shown in Figs. and 4 the platform supported by the legs2 and in turn supporting the hood 3 are the same as in thepreviousconstruction. Each side wall of the hood 3 is provided withopenings as shown 'a't'20 and 21. Theopening 20 is connected b theconduit 22 to the suction side of the b ower 2'3. The delivery side ofthe blower is connected through the conduit 24 which delivers into" adust bag (not shown but similar to bag 14 Fig. 1) ,within the -dusthouse 25. The purged air after passin through the dust bag isdeliveredthrough conduit flfi itotheopening 21. ,In

this form of construction the current of air travels transversely of thehood 3 and the object to be cleaned such as the mattress is placed onplatform 1. The dust is loosened and removed from the mattress bybeating it and is taken up by the transverse current of air whichcarries it to the dust bag 30. The cleaned air is then carried throughconduit 26 to hood 3 where it may again. become dust laden. In this formof device it has also been found that the object can be cleaned withoutthe escape of dust into the surrounding atmosphere.

I am well aware that numerous changes in the details of construction andrelativeassociation of parts will. readily occur" to those skilled inthe art without departing from the principles of this invention and I donot therefore desire to be limited to the constructions shown forpurposes of illustration, but rather to the scope of my;invention as itis defined in the appended claims.

Having now disclosed the principles of my invention, what I seek to'secure by United StatesLett'ers Patent is:-

1. In a device of .the type described, the combination of a platformhaving an opening therein, a brush in registry with said opening, a hoodover-said platform having a discharge opening,- a conduit systemcon-'nected to the platform opening, and to the hood discharge opening,means for creating a continuous current 'ofair in said system, and meansfor removing dust from the air leaving said discharge opening. l

2. In a device of the type described, the

combination with a platform, an open ended hood support on said platformhaving an aperture in one wall thereof and means on said platform forloosening and removing.

the dust from the article to be cleaned of a circulatorysystem openingat one end into the aperture in the hood and opening at the other endadjacent .said means, means in said system for'creating a current of airand means also in said system for removing the dust from the current ofair.

3. In a device of the type described,means for supporting an object tobe cleaned, means for removingdust, therefrom, means 'for creating acontinuous current of air in the form of asubstantially closed circuit,

meansfor' guiding said current past said removing means to'carry thedust in a substantially confined path, and means in the path of saidcurrent for collecting the dust without interfering with the substantialcontinuity of saidfcurrent. a

4. In a cleaning machinethe combination with a platform, an open'endedhood supported on said platform and a plurality of revolving brushessup-ported below said platform and projecting therethrough of a conduitsystem opening at one end into said hoodand opening atlthe other endthrough the openingsin said platform, means in said f conduit system forcreating a current of air' "I and m'eans in said system for ,air of dustand the like.
